연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A refrigerated merchandiser includes a case defining a product display area and having a base, a lower flue, a first air passageway, and a second air passageway. The first air passageway and second air passageway are in fluid communication with the lower flue and with the product display area. A fan plenum has an outlet defining a first plane. A second plane is defined perpendicular to the first plane and passing through the center of a fan aperture. The fan plenum further includes an airflow divider with a first wall member and a second wall member positioned to direct a first portion of the airflow to the first air passageway and a second portion of the airflow to the second air passageway. The space between the first wall member and the second wall member defines an area, the greater portion of which is to one side of the second plane.

1. A refrigerated merchandiser comprising: a case defining a product display area and including a base, a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area;an evaporator positioned in the first air passageway;a fan assembly positioned in the base in fluid communication with the lower flue to generate an airflow; anda fan plenum into which the fan assembly is disposed, the fan plenum including a wall having a first portion with a first face, a second portion with a second face, and an intermediate portion connecting the first portion to the second portion and having an intermediate face, andan airflow divider to direct a first portion of the airflow to the first air passageway and to direct a second portion of the airflow to the second air passageway, the airflow divider including a first wall member extending to the first face and a second wall member extending to the intermediate face, wherein the proportion of air between the first portion and the second portion is a function of the position and geometry of the airflow divider. 2. The refrigerated merchandiser of claim 1, wherein the fan assembly includes a fan having a plurality of fan blades, wherein the airflow divider and the plurality of fan blades define a clearance therebetween, and wherein interaction between the first portion and the second portion of the airflow is dependent on the clearance. 3. The refrigerated merchandiser of claim 1, wherein the fan assembly includes an axial flow fan. 4. The refrigerated merchandiser of claim 1, wherein the fan plenum includes a top wall secured to the first portion and to the second portion, and wherein the airflow divider partitions the fan plenum into a first duct and a second duct, the first duct in communication with the first air passageway and the second duct in communication with the second air passageway. 5. The refrigerated merchandiser of claim 4, wherein the top wall includes a fan aperture for receiving a fan having a plurality of fan blades, and wherein the fan aperture is equidistant from the first portion of the wall and the second portion of the wall. 6. The refrigerated merchandiser of claim 4, wherein the first wall member and the second wall member are orthogonal to the top wall. 7. The refrigerated merchandiser of claim 6, wherein an angular separation β of the first wall member from the second wall member ranges from about 30° to about 90°, whereby the quantity of air discharged to the first passageway with respect to the second passageway is proportional to β. 8. The refrigerated merchandiser of claim 7, wherein the angular separation of the first wall member from the second wall member is 60°. 9. A refrigerated merchandiser comprising: a case defining a product display area and including a base, a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area;an evaporator positioned in the first air passageway;a fan assembly positioned in the base in fluid communication with the lower flue to generate an airflow; anda fan plenum with a fan aperture into which the fan assembly is disposed, the fan aperture having a center, the fan plenum having an outlet defining a first plane, wherein a second plane is defined perpendicular to the first plane and passing through the center of the fan aperture, the fan plenum further including an airflow divider with a first wall member and a second wall member positioned to direct a first portion of the airflow through the outlet to the first air passageway and to direct a second portion of the airflow through the outlet to the second air passageway, and wherein the space between the first wall member and the second wall member defines an area, the greater portion of which is to one side of the second plane. 10. The refrigerated merchandiser of claim 9, wherein the fan assembly includes a fan having a plurality of fan blades, wherein the airflow divider and the plurality of fan blades define a clearance therebetween, and wherein interaction between the first portion and the second portion of the airflow is dependent on the clearance. 11. The refrigerated merchandiser of claim 9, wherein the fan assembly includes an axial flow fan. 12. The refrigerated merchandiser of claim 9, wherein the fan plenum further includes a side wall having first and second ends, and wherein the first plane is coincident with the first and second ends. 13. The refrigerated merchandiser of claim 12, wherein the fan plenum includes a top wall secured to the side wall, and wherein the airflow divider partitions the fan plenum into a first duct and a second duct, the first duct in communication with the first air passageway and the second duct in communication with the second air passageway. 14. The refrigerated merchandiser of claim 12, wherein the center of the fan aperture is equidistant from the first and second ends of the side wall. 15. The refrigerated merchandiser of claim 9, wherein an angular separation β of the first wall member from the second wall member ranges from about 30° to about 90°, whereby the quantity of air discharged to the first passageway with respect to the second passageway is proportional to β. 16. The refrigerated merchandiser of claim 9, wherein the fan plenum further includes a side wall having a first portion with a first face, a second portion with a second face, and an intermediate portion connecting the first portion to the second portion and having an intermediate face, and wherein the first wall member extends to the first face and the second wall member extends to the intermediate face. 17. The refrigerated merchandiser of claim 16, wherein the intermediate face is bisected by a midline, and further wherein the second wall member extends to the midline. 18. A fan plenum for a refrigerated merchandiser, the refrigerated merchandiser including a case defining a product display area and including a lower flue, a first air passageway, and a second air passageway, the first air passageway and second air passageway in fluid communication with the lower flue and with the product display area, the fan plenum comprising: a top wall including a fan aperture for receiving a fan having a plurality of fan blades, the fan aperture having a center;an outlet defining a first plane, wherein a second plane is defined perpendicular to the first plane and passing through the center of the fan aperture; andan airflow divider with a first wall member and a second wall member positioned to direct a first portion of the airflow through the outlet to the first air passageway and to direct a second portion of the airflow through the outlet to the second air passageway, and wherein the space between the first wall member and the second wall member defines an area, the greater portion of which is to one side of the second plane. 19. The fan plenum of claim 18, wherein an angular separation β of the first wall member from the second wall member ranges from about 30° to about 90°, whereby the quantity of air discharged to the first passageway with respect to the second passageway is proportional to β. 20. The refrigerated merchandiser of claim 18, wherein the fan plenum further includes a side wall having first and second ends, and wherein the first plane is coincident with the first and second ends.
